This particular error happens on 10.6.8 as well. There are workarounds for this on the web that I have applied to other ports who use this incantation. Just have to see if I can remember which port that was now :>

Your log is hard to read because of interleaved errors due to parallel building.

Here's the log from the buildbot for 10.7:

​https://build.macports.org/builders/ports-10.7_x86_64_legacy-builder/builds/60620/steps/install-port/logs/stdio

The error is:

error: expected method to read array element not found on object of type 'NSArray *'
        NSString *path = (NSString *) paths[0];
                                      ^
1 error generated.

According to ​Stack Overflow, this needs the 10.8 SDK or later. That is easy to fix on 10.7 where Xcode includes the 10.8 SDK, and harder to fix on 10.6 and earlier where Xcode does not, though I am working on a solution.

Here's the log from the buildbot for 10.6:

​https://build.macports.org/builders/ports-10.6_i386_legacy-builder/builds/38548/steps/install-port/logs/stdio

That might be a different error.

Replying to ryandesign:

Here's the log from the buildbot for 10.7: ...

Yes, the log is the one that is linked to in the terminal after the error.

Thanks for looking into it.

IIRC, the fix for older ObjC is to change this:

NSString *path = (NSString *) paths[0];

to this:

NSString *path = (NSString *) [paths objectAtIndex:0];

[kencu (Ken)]

Yeah, looks like that fixes it, at least on 10.7.5:

$ port -v installed physfs
The following ports are currently installed:
  physfs @3.0.1_0 (active) platform='darwin 11' archs='x86_64' date='2018-03-20T11:17:42-0600'

Thanks, I reported the problem and your fix to the developers:
